Method for improving temperature uniformity of blast drying oven

According to different dry materials, the drying ovens are mainly divided into two types: vacuum drying ovens and electric blast drying ovens. Among them, electric blast drying oven is a commonly used experimental equipment and has been widely used in electronic communication, medical and chemical industries. The temperature uniformity parameter of the electric blast drying oven has two standards. The natural convection drying oven experimental instrument is the upper limit of the operating temperature multiplied by 3%, and the forced convection drying oven experimental instrument is the upper limit of the working temperature multiplied by 2.5%. The following is a brief explanation of the method for improving temperature uniformity of blast drying oven.

Laboratory equipment – the airflow structure of the blast drying oven directly determines the temperature uniformity. The drying oven generally uses a single air duct to organize the airflow, and the airflow is mainly from the centrifugal fan system. The improvement is mainly for the volute and the return air outlet. Redesign the volute according to the Archimedes vortex principle and increase the air volume at the return air outlet and the wind pressure and wind speed at the outlet.

2. Determination of heater position

In order to obtain good temperature uniformity, it is a key node to test whether the heat of the heater of the blast drying oven can be evenly brought into the studio by the airflow. So it is extremely important to be ready to determine the position of the heater.

3. Improvement of sample shelf

The shelf of the old experimental instrument drying oven is generally punched with a plate. In order to ensure the strength, the aperture density of the shelf is small, which also increases the resistance of the air circulation, thereby affecting the temperature uniformity. Changing the shelf to a wire structure can effectively solve this problem.

4. Improvement of the door locking device

In the past, high-temperature drying ovens generally used single-point door locking devices. Such locking devices have certain limitations. When the high temperature reaches 400 degrees or more, the deformation of the door will lead to a decrease in sealing performance and affect the temperature uniformity of the drying oven of the experimental instrument. It has been found through experiments that this problem can be effectively solved if the locking device is improved to double-point locking.

If your dishwasher goes out, you have got to wash plates by hand. Microwave foods could be meant by it for the remainder of the week, if your range fails. Combining both an oven and a stovetop in one appliance makes collections quite versatile when it comes to cooking.
